Patent CA-2369846-A1 (CA)
Title: Interleaved wordline architecture
Inventor: KURJANOWICZ WLODEK
IPC: H01L21/8242
Filed: 2002-01-31
Abstract: A high-density folded bitline memory array architecture is disclosed. High memory cell packing density is achieved by dividing polysilicon wordlines into short individual segments in the folded bitline scheme. Each wordline segment forms the gate of one or two DRAM memory cell transistors, and each segment is connected to a metal wordline, or conductor having low resistivity. By eliminating spaces between the memory cells due to passing wordlines, a cell arrangement and density similar to open bitline schemes is achieved. Further packing is obtained by arranging two columns of memory cells parallel to each bitline, each column offset with the other by a predetermined pitch. Therefore, by increasing the number of memory cells connected to each complementary bitline pair, each bitline pair can be cut in half and connected to its own bitline sense amplifier to reduce the bitline capacitance. Hence the memory cell architecture of the present invention occupies less area, and operates with faster speed than memory cell architectures of the prior art.

Patent CA-2374843-A1 (CA)
Inventor: RUDBERG MIKAEL
IPC: H03M1/10
Filed: 2000-05-29
Abstract: An analog-to-digital converter (ADC) has a histogram based correction of static errors. In a control and calculating unit (23) of the converter thus the counts of uncorrected digital output codes are stored in a memory (51). From the stored counts a model distribution is determined in a calculation unit, e.g. by estimating an expected gaussian distribution. The model distribution is compared to the measured counts and relative errors of the counts are calculated, the relative errors indicating errors in coarse reference levels. The errors are used for calculating correction terms (L(A) ) stored in a correction table (47). The correction terms are used by an outpu t calculating unit (43') to calculate corrected, more accurate output codes. F or a parallel ADC device having several cells, the histograms in the cells can be used to correct for gain and offset errors. Also, the histogram can be used in a built-in self test. A reference level generator can be only partially comm on to the cells in a parallel ADC providing accurate coarse levels without cros s- talk.

Title: Stimulus output monitor and control circuit for electrical tissue stimulator
Inventor: CARTER PAUL MICHAEL
IPC: A61N1/08
Filed: 1999-06-11
Abstract: There is described an electrical tissue stimulating device, such as a cochlear prosthesis, which includes circuitry (47) for monitoring the build-up of undesirable residual voltages between stimulation electrodes. In the event that such a condition is sensed then an overvoltage signal is generated and transmitted to a switch controller (48). In response the switch controller controls electrode switches (42) in order to suppress stimulation of the monitored electrode(s) until the undesirable residual voltage has fallen to an acceptable level. As a result the build-up of undesirable inter-electrode voltages is reduced.

Title: Process for the preparation of quasi-crystalline boehmites
Inventor: JONES WILLIAM
IPC: C01F7/448
Filed: 2000-08-11
Abstract: The present invention pertains to an improved process for the preparation of quasi-crystalline boehmite. In this improved process a quasi-crystalline boehmite precursor is aged at a pH below 7, preferably under hydrothermal conditions. It was found that when conducting the preparation processes for quasi-crystalline aluminas described in the prior art at a pH below 7 and under hydrothermal conditions instead of the high pH and thermal ageing used in the prior art, QCBs with higher crystallinity are obtained. In the process according to the invention additives may be added to the quasi-crystalline boehmite precursor. This results in a high quality QCB with additives in a homogeneously dispersed state.  Suitable additives are compounds containing elements selected from the group of rare earth metals, alkaline earth metals, transition metals, actinides, silicon, gallium, boron, and phosphorus.

Title: Prosthesis for abdominal aortic aneurysm repair
Inventor: BANAS CHRISTOPHER E
IPC: A61F2/06
Filed: 2000-09-21
Abstract: The device of the present invention comprises a bifurcated graft fabricated from expanded PTFE (ePTFE). The inventive device is double walled so that following insertion into an aneurysm, fluid can be injected between the walls to expand the device thereby opening the inner tubular graft for receiving blood flow and locking the device into place in the aorta. The injected fluid may polymerize so that the device is permanently held in its expanded form.  One embodiment of the device is fabricated with packets or channels. After the device is delivered and expanded additional stiffening struts can be inserted into these pockets. In this way the basic device can be furled and tightly compressed for delivery (something not possible with a stent containing device). After the device is expanded, a stent-like structure can be inserted endovascularly giving the strength and resiliency of a stent-containing prosthesis.

Abstract: A medical procedure kit incorporates one or more surgical tools necessary to perform at least part of a medical procedure, along with a container having a quantity of a medical adhesive. Medical adhesives are useful as an alternate or an adjunct to surgical sutures and/or staples in wound closure, as well as for covering and protecting surface wounds such as lacerations, abrasions, burns, stomatitis, sores, minor cuts and scrapes, and other wounds. As such, the inclusion of such an adhesive into a composite medical procedure kit can be of great assistance to a medical doctor or surgeon by providing in single kit form, tools necessary to complete many medical procedures, without having to use multiple procedure kits. The adhesive may be independently sterilized and wrapped from the other surgical tools of the resultant kit, and then associated into kit form, or assembled and sterilized together as a unitary kit.  When the adhesive is incompatible with sterilizing procedures of the other components of the kit, the adhesive may be pre-sterilized and protected by a sterilization barrier that shields the adhesive from exposure to the sterilization process used to sterilize other tools of the procedure kit. The adhesive is preferably a 1,1-disubstituted ethylene monomer, such as an alpha-cyanoacrylate.
